A foundry has a fixed daily cost of Rs 50,000 whenever it operates and a variable cost of Rs 800Q, where Q is the daily production in tonnes. What is the cost of production in Rs per tonne for a daily production of 100 tonnes?
Fixed Cost= Rs. 50000
Daily Production = 100 tonnes
Variable Cost = Rs 800Q = Rs 800 x 100 = Rs 80000
Total Cost = Fixed Cost + Variable Cost = Rs 50000+ Rs 80000= Rs 130000
Therefore, Cost of Production per tonne= Rs 130000/100 tonnes= Rs 1300/ tonne

The smallest angle of a triangle is equal to two thirds of the smallest angle of a quadrilateral. The ratio between the angles of the quadrilateral is 3:4:5:6. The largest angle of the triangle is twice its smallest angle. What is the sum, in degrees, of the second largest angle of the triangle and the largest angle of the quadrilateral?
Let angle of quadrilateral be 3x, 4x, 5x, 6x
Sum of angles of quadrilateral = 360 = 3x+4x+5x+6x = 18x
x= 360/18 =20
The smallest angle of triangle is ⅔ of smallest angle of quadrilateral = ⅔ (3x)
= 2x = 40
Largest angle of triangle is twice the smallest angle of triangle= 2x40 = 80
Therefore, second largest angle of triangle = 180Largest Angle Smallest Angle
= 180  80 40 = 60
Sum of second largest triangle and largest angle of quadrilateral = 60+ 6x
= 60+ 6x20
=180
